✔ 最佳答案
Serial number is a unique ID (identiry) of the product.
It appears in most electronic appliance such as TV, DVD, Camera, MP Phone, CD, Notebook etc.
You may check with the box, and the Digital Camera Body (bottom part or inside the battery cover, Card Cover etc.) The Serial No. (S/N # would be sticked firmly by a lable).
Apart from the S/N #, there should be some other no. such as EAN no. or UPC no. for transportation and inventory checking, as well as for the selling point check for the price.
